IMPROVEMENT lN BOTTLE-STOPPERS.

Specification forming part of Letters Patent No. 185,694, dated December26, 1876; application filed October 30, 1876.

' To all whom t may concern.'

Be it known that I, STEPHEN S. NEWTON, of Binghamton, in the county ofBroome and State of New York, have invented a new and valuableImprovement in Bottle Stoppers; and I do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation of the saine, reference being had tothe annexed drawings,making a part of this specification, and to the letters and figures ofreference marked thereon.

Figure 1 of the drawings is a representation of a vertical section ot astopper embracing my invention, and Fig. 2 is a vertical section of amodification thereof. Fig. 3 represents a further modiication.

The same letters indicate like parts in the figures.

A represents a cylindrical plug, of cork or other suitable material,made, by preference, tapering in form, and adapted to fit within themouth ot' a bottle. B is a tube fitting closely a hole cut for itsreception centrally inb the plug A. The outside of the tube B isscrewthreaded, in order that it may the better take hold ofthe plug andwithdraw it from a bottle, and has a flange or cap, b, attached to itsupper end, which llange is, by preference, milled upon its edge tofacilitate handling. The interior of tube B is also screw-threaded. asindicated in the drawings, and is provided at its lower end with avalve-seat, b. G is the delivery nozzle or tip, the hole through which(terminates, near its lower end, in a number ot' ports, c. D d is aball-valve. By preference, I make this valve of rubber, and secure it tothe lower end of the screw tip or nozzle O. For this purpose, Isometimes form the lower end of this screwnozzle with a cup shapedcavity, c1, inthe lower end, the mouth of the cavity being somewhatcontracted, so that when the rubber ball-valve has been compressed andforced-in position it cannot be readily removed from its proper place,this feature of construction being plainly shown in Fig. 3.

When, however, a metallic ballvalve is used, the lower end of thescrew-tip may be slitted, as shown in Fig. 2, so that the prongs or jawsc2 thus formed can be opened a little, the ball inserted, and the jawsthen closed, and the ball thereby held in place.

Under soine circumstances I may find it advisable to leave the balldetached, and merely press it upon the valve-seat by screwing down thescrew-tip, this construction and arrangement of parts being especiallyadapted for use when a metal ball-valve is used, because it will insurethat the valve shall be properly seated upon the valve-seat b', eventhough there besome slight imperfection in the construction or operationot' the parts of the device.

In the construction shown in Figs. 2 and 3 the ball-valve is somewhatsmaller' than internal diameter of the tube B. Thus an annular space isleft around the valve, through which the liquid can pass freely, and aconvenient place for the ports c is made around the neck, by which theball valve D d is connected with the tip G. This construction alsofacilitates the application of an outer covering or packing, d, to theinner portion D of the valve. (See Fig. 3.)

What I claim is- The combination of the ti C and ball-valve l) with theplug B, provide With the valveseat b', substantially as set forth.

In testimony that I claim the foregoing I have hereunto subscribed myname in the presence ot' two witnesses.
